Using the RS 180
Enhancing the speech intelligibility
The speech intelligibility can be enhanced by activating a dynamic compression system (Automatic Level Control).
When activated, the automatic level control evens out volume differences, i.e. it reproduces soft passages louder and decreases loud sounds. This seems to put the speech in the foreground, making it easier to understand.
To activate the automatic level control:
Press the ALC button on the transmitter. The ACL button is backlit in green.
